5.1.5 Power allocation for PUCCH-SCell

36.2133GPPEvolved Universal Terrestrial Radio Access (E-UTRA)Physical layer proceduresRelease 17TS

If a UE is configured with a PUCCH-SCell, power allocation for serving cells in the primary PUCCH group and secondary PUCCH group is performed according to Clause 5.1.4.1, with the following exceptions:

– the term ‘MCG’ is replaced by ‘primary PUCCH group’;

– the term ‘SCG’ is replaced by ‘secondary PUCCH group’;

and is the linear value of the UE total configured maximum output power defined in [6] in subframe/slot/subslot i; and

.

For a UE capable of simultaneous transmission of different uplink signal durations to different serving cells as indicated by UE capability simultaneousTx-differentTx-duration, if the UE is configured with a PUCCH-SCell and configured with different values of higher layer parameter ul-STTI-Length for serving cells in the primary PUCCH group and secondary PUCCH group, and if the total transmit power of the UE would exceed , the UE drops the following channels from the highest serving cell index to the lowest serving cell index in order until the total transmit power of the UE would not exceed which in that case, the UE would not drop any more channels or until there are only PUSCH/PUCCH transmissions of the same duration remaining in which case the corresponding power scaling rules described in Clause 5.1.1 apply:

– subframe-PUSCH without HARQ-ACK of the secondary PUCCH group

– subframe-PUSCH without HARQ-ACK of the primary PUCCH group

– slot-PUSCH without HARQ-ACK of the secondary PUCCH group

– slot- PUSCH without HARQ-ACK of the primary PUCCH group

– subslot-PUSCH without HARQ-ACK and without DMRS of the secondary PUCCH group

– subslot-PUSCH without HARQ-ACK and without DMRS of the primary PUCCH group

– subslot-PUSCH without HARQ-ACK and with DMRS of the secondary PUCCH group

– subslot-PUSCH without HARQ-ACK and with DMRS of the primary PUCCH group

– subframe-PUSCH with HARQ-ACK or subframe-PUCCH of the secondary PUCCH group

– subframe-PUSCH with HARQ-ACK or subframe-PUCCH of the primary PUCCH group

– slot-PUSCH with HARQ-ACK or slot-PUCCH of the secondary PUCCH group

– slot-PUSCH with HARQ-ACK or slot-PUCCH of the primary PUCCH group

– subslot-PUSCH with HARQ-ACK or subslot-PUCCH of the secondary PUCCH group

– subslot-PUSCH with HARQ-ACK or subslot-PUCCH of the primary PUCCH group

The HARQ-ACK of a dropped channel is transmitted on the channel of the same PUCCH group to be transmitted with highest priority.

If the UE is not configured with a PUCCH-SCell but configured with higher layer parameter ul-STTI-Length, and if the total transmit power of the UE would exceed , the UE above dropping rules would apply by removing the channels corresponding to the secondary PUCCH group.
